If you love dystopeas as much as I do, then this will probably end up on your list of favorite's. I thought it was so good. The characters were easy to fall in love with and so intriguing, you're not going to be able to stop reading. I love the world itself, the republic of America is so cool and captivating. I especially love how she uses cities we know of today, the whole book takes place in LA, and since I've been to LA its so cool to imagine the city's future.
This book is so action packed, you won't be able to put it down. I've grown to love Marie Lu's writing style, it makes you feel like you're watching a movie while reading it.
The plot itself may have been one of the best parts. I love the protagonists, June and Day, and that ones a Republic prodigy and ones a wanted criminal. You get the same story from two very different point of views, allowing you to become obsessed with both characters. Definitely a must-read.
